From version 5.5 some [[object-oriented programming]] features were introduced: [[Class (computer programming)|classes]], [[Inheritance (object-oriented programming)|inheritance]], [[Constructor (object-oriented programming)|constructors]] and [[Destructor (computer programming)|destructors]].<ref name="tp55">{{cite web |url=http://edn.embarcadero.com/article/20803 |title=Antique Software: Turbo Pascal v5.5 |first=David |last=Intersimone |date=2002-02-21 |publisher=Embarcadero Technologies |access-date=2010-11-09 |archive-url=https://web.archive.org/web/20101124090934/http://edn.embarcadero.com/article/20803 |archive-date=2010-11-24 |url-status=dead}}</ref> The IDE was already augmented with an object browser interface showing relations between objects and methods and allowing programmers to navigate the modules easily. Borland called its language ''[[Object Pascal]]'', which was greatly extended to become the language underlying [[Delphi (software)|Delphi]] (which has two separate OOP systems).
The name "Object Pascal" originated with the Pascal extensions developed by [[Apple Computer]] to program its [[Apple Lisa|Lisa]] and [[Macintosh 128K|Macintosh]] computers. Pascal originator [[Niklaus Wirth]] consulted in developing these extensions, which built upon the [[record (computer science)|record]] type already present in Pascal.
